Revelation 20:6-8 American Standard Version (ASV)

6. Blessed and holy is he that hath part in the first resurrection: over these the second death hath no power; but they shall be priests of God and of Christ, and shall reign with him a thousand years.

7. And when the thousand years are finished, Satan shall be loosed out of his prison,

8. and shall come forth to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to the war: the number of whom is as the sand of the sea.
